WebScientific Computing and Imaging Institute WebSep 24, 2012 · 3. The curve of a density estimator is just the sum of all the kernels, in your case a gaussian (divided by the number of points). The derivative of a sum is the sum of the derivatives and the derivative of a constant times a function is that constant times the derivative. So the derivative of the density estimate at a given point will just be ...
